前言

首先，跟守護在作者公眾號和私信作者催更的朋友們道個歉。疫情的原因，公司從年初到現在一直處於996+的高壓模式，導致公眾號更新頻率較低。而且作者每更新一篇原創公眾號，既要對自己沉淀知識負責，也要對願意和作者一起探討一起學習一起進步的小伙伴兒們負責，防止誤人子弟。所以作者的每一篇原創，都是作者在有限時間內仔細推敲后的產物，希望大家可以理解。

Talk is Cheap!

前面分享的幾個章節，差不多把實際用到的控件和容器的封裝、擴展、重繪都舉例到了(后續如果還有其他特例，作者也會更新進來)。今天要分享的依然是“Fucking ERP”系列中比較重要的環節——流程圖。

本章的流程圖並非工作流，winform在市面上有很多經典的工作流組件比如微軟的WWF，還有很多開源自主研發的工作流組件等等，后續作者實際用到的話也會分享出來和大家一起探討。此處分享的流程圖，主要是"標識"的作用，主要用來表示業務數據的流轉，具體數據如何流轉，都需要各位后台自行處理（說白了，就是從A表查出數據，插入到B表，然后更新A表標識罷了。）

Show me the Code!

首先，界面加載的時候，初始化控件可用性，以及所有模塊列表

private void frmWorkFlow_Load(object sender, EventArgs e)
{
    //創建大模塊
    CreateModule();
    this.TabPage1.PageVisible = false;
    this.TabPage2.PageVisible = false;
    this.TabPage3.PageVisible = false;

    this.kzxsBtnAddButton.Enabled = false;
    this.kzxsBtnAddLabel.Enabled = false;
    this.kzxsBtnAddLine.Enabled = false;

    this.Btn_SaveButton.Enabled = false;
    this.Btn_SaveLabel.Enabled = false;
    this.Btn_SaveLine.Enabled = false;

為了滿足演示效果，本位都用DataTable來模擬數據庫操作。初始化模塊菜單方法如下：

 //創建主目錄
public void CreateModule()
{
    //此處拿DataTable來存儲數據庫的所有菜單節點，此處用銷售模塊來舉例
    DataTable dtSalesOrder = new DataTable();
    dtSalesOrder.Columns.Add("sID", typeof(Guid));
    dtSalesOrder.Columns.Add("sModel", typeof(string));
    dtSalesOrder.Columns.Add("iOrder", typeof(int));
    dtSalesOrder.Rows.Add(new object[] { Guid.NewGuid(), "銷售模塊", 1 });

    DataRow[] dr = dtSalesOrder.Select("", "iOrder");

    //存在子菜單生產樹結構
    if (dr.Length > 0)
    {
        foreach (DataRow row in dr)
        {
            DevExpress.XtraEditors.SimpleButton sb = new DevExpress.XtraEditors.SimpleButton();
            sb.Name = row["sID"].ToString();
            sb.Text = row["sModel"].ToString();
            sb.Tag = row["sModel"].ToString();
            sb.TabIndex = int.Parse(row["iOrder"].ToString());
            sb.Dock = DockStyle.Top;
            sb.Height = 25;
            sb.Click += onBtnClick;
            panelControl1.Controls.Add(sb);

        }
    }
}

模塊按鈕綁定了點擊事件，用於觸發當前選擇的菜單的流程圖（代碼邏輯已經添加，時間有限，本文不做處理，如有疑問，可公眾號私信作者一起探討）

private void onBtnClick(object sender, EventArgs e)
  {
      sModel = ((DevExpress.XtraEditors.SimpleButton)sender).Name.ToString().Trim();
      sModelName = ((DevExpress.XtraEditors.SimpleButton)sender).Text.ToString().Trim();
      //根據選擇的菜單模塊，加載當前菜單的流程圖
      CreateFlowMap(((DevExpress.XtraEditors.SimpleButton)sender).Name.ToString().Trim(), ((DevExpress.XtraEditors.SimpleButton)sender).Text.ToString().Trim());
  }

創建流程圖部分方法如下（有需要源碼可關注作者公眾號，私信作者免費獲取）：

//創建流程圖
public void CreateFlowMap(string sModelID, string sModelName)
{
    //查找是否存在流程圖   
    string sFilter = "sModelCode =  '" + sModelID + "'";
    TabControl2.Visible = true;
    Boolean bExists = false;
    //查找模塊流程圖是否存在
    foreach (DevExpress.XtraTab.XtraTabPage tabPage in TabControl2.TabPages)
    {
        if (tabPage.Name == sModelID)
        {
            tabPage.PageVisible = true;
            TabControl2.SelectedTabPage = tabPage;
            bExists = true;
        }
        else
        {
            tabPage.PageVisible = false;
        }
    }
    //不存在需要增加頁面
    if (!bExists)
    {
    .....

You say a JB without pictures ！無圖言X，先給大家看看設計圖

圖片展示解析：

1.左側欄初始化動作，加載所有系統模塊

2.右側上部分為操作欄，設計按鈕處理當前選中的菜單模塊，用於加載/新增/刪除當前模塊的流程圖

3.右側左邊部分為繪制工具欄，此處只拿繪制直線(或帶箭頭的直線),Label（流程注釋），按鈕來舉例子。

4.右側下部分為繪制工具欄的屬性配置，點擊保存，呈現繪制結果如圖右側中間部分

5.流程圖展示區，用於加載或繪制流程圖

（以上因篇幅和時間限制未做詳細測試，主要實現功能為主舉個例子，作者繪制期間也有遇到不完善的地方，后續有時間在優化）

代碼沒有太大難度(需要源碼研究可關注作者公眾號，私信作者免費獲取)，主要跟大家分享下繪制流程模塊吧。

(帶箭頭的)直線的繪制

Talk is Cheap,直接上代碼：

  KzxLine line = new KzxLine();

  bAddLine = true;
  line.Name = "Line";
  line.Tag = "";
  line.lineWidth = int.Parse(this.cmb_LineWidth.Text.ToString());
  string sColor = this.cmb_ColorLine.Text.ToString().Trim();
  switch (sColor)
  {
      case "Black":
          line.LineColor = KzxLine.ColorType.Black;
          break;
      case "Blue":
          line.LineColor = KzxLine.ColorType.Blue;
          break;
      case "Green":
          line.LineColor = KzxLine.ColorType.Green;
          break;
      case "Lime":
          line.LineColor = KzxLine.ColorType.Lime;
          break;
      case "Red":
          line.LineColor = KzxLine.ColorType.Red;
          break;
      case "Yellow":
          line.LineColor = KzxLine.ColorType.Yellow;
          break;
      default:
          line.LineColor = KzxLine.ColorType.Black;
          break;
  }
  line.IsSolid = !this.chk_Solid.Checked;
  switch (this.cmb_ArrowType.Text.ToString().Trim())
  {
      case "Start":
          line.ArrowPosition = KzxLine.ArrowType.Start;
          break;
      case "End":
          line.ArrowPosition = KzxLine.ArrowType.End;
          break;
      case "All":
          line.ArrowPosition = KzxLine.ArrowType.All;
          break;
      case "None":
          line.ArrowPosition = KzxLine.ArrowType.None;
          break;
  }
  if (this.chk_Horizon.Checked)
  {
      line.LineStyle = KzxLine.LineType.Horizontal;
      line.Left = int.Parse(this.edt_LeftLine.Text.ToString());
      line.Top = int.Parse(this.edt_TopLine.Text.ToString());
      line.Width = int.Parse(this.edt_WidthLine.Text.ToString());
      line.Height = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10;
  }
  else
  {
      line.LineStyle = KzxLine.LineType.Vertical;
      line.Left = int.Parse(this.edt_LeftLine.Text.ToString());
      line.Top = int.Parse(this.edt_TopLine.Text.ToString());
      line.Width = int.Parse(this.cmb_LineWidth.Text.ToString()) * 2 + 10;
      line.Height = int.Parse(this.edt_HeightLine.Text.ToString());
  }
  line.Visible = true;

  line.Click += onClick;
  MoveClass.BarcodeControl(line);
  if (bFirstControl)
  {
      MoveClass.BarcodeCreate();
      bFirstControl = false;
  }
  this.TabControl2.Enabled = true;
  this.TabControl1.SelectedTabPage = TabPage3;
  this.TabPage3.PageVisible = true;

  this.kzxsBtnAddButton.Enabled = true;
  this.kzxsBtnAddLabel.Enabled = true;
  this.kzxsBtnAddLine.Enabled = true;

其中KzxLine是作者封裝的用戶控件,（如有需要，請關注公眾號私信作者，源碼免費贈送）部分代碼如下：

protected override void OnPaint(PaintEventArgs e)
{
    base.OnPaint(e);
    //e.Graphics.DrawLine(new Pen(lineColor, lineHeight), 1, 1, this.Width, lineHeight);

    AdjustableArrowCap lineCap = new AdjustableArrowCap(5, 5, true);
    Pen p = new Pen(lineColor, 1);

    string sColor = "";
    if ((int)color == 0) 
    {
        sColor = "Black";
    }
    if ((int)color == 1)
    {
        sColor = "Red";
    }
    if ((int)color == 2)
    {
        sColor = "Yellow";
    }
    if ((int)color == 3)
    {
        sColor = "Blue";
    }
    if ((int)color == 4)
    {
        sColor = "Green";
    }
    if ((int)color == 5)
    {
        sColor = "Lime";
    }
   
    p.Color = Color.FromName(sColor);
    p.Width = LWidth;

    if ((int)ArrowP == 1)
    {
        p.CustomStartCap = lineCap;
    }
    else
        if ((int)ArrowP == 2)
        {
            p.CustomEndCap = lineCap;
        }
        else
            if ((int)ArrowP == 3)
            {
                p.CustomStartCap = lineCap;
                p.CustomEndCap = lineCap;
            }

    if (!Solid)
    {
        float[] dashValues = { 5, 2, 5, 2 };
        p.DashPattern = dashValues;
    }

    int iLeft = 1;
    int iTop = 1;
    int iWidth = 1;
    int iHeight = 1;

    if ((int)sTyle == 0)
    {
        iLeft = 1;
        iTop = LWidth * 2 + 5;
        iWidth = this.Width;
        iHeight = LWidth * 2 + 5;
    }
    else
    {
        iLeft = LWidth * 2 + 5;
        iTop = 1;
        iWidth = LWidth * 2 + 5;
        iHeight = this.Height;
    }
    e.Graphics.DrawLine(p, iLeft, iTop, iWidth, iHeight);
    p.Dispose();
}

點擊如圖"箭頭/直線"按鈕后，下面會顯示控件的屬性配置區域，設置好后點擊保存，就會把繪制好的控件添加到流程圖展示區。保存事件如下：

private void Btn_SaveLine_Click(object sender, EventArgs e)

        line.Tag = "";
        line.lineWidth = int.Parse(this.cmb_LineWidth.Text.ToString());
        string sColor = this.cmb_ColorLine.Text.ToString().Trim();
        switch (sColor)
        {
            case "Black":
                line.LineColor = KzxLine.ColorType.Black;
                break;
            case "Blue":
                line.LineColor = KzxLine.ColorType.Blue;
                break;
            case "Green":
                line.LineColor = KzxLine.ColorType.Green;

        }
    }
}

因所有繪制控件都綁定了拖拽事件，所以可以在流程圖展示區隨意拖拽部署顯示控件（效果見下圖）。

Label(注釋)控件封裝

  /// <summary>
    /// 標簽驗證
    /// </summary>
    public partial class KzxLabel : KzxBaseControl

Label無需重繪只需封裝，初始化綁定多語言即可。

  public void LayoutControl()
  {
      BindingEvent(this, PluginInfoTable);
      if (this.DesignMode == true)
      {
          this.DesigeCaption = GetLanguage(this.MessageCode, this.DesigeCaption);
      }
  }

  /// <summary>
  /// 綁定事件
  /// </summary>
  /// <param name="eventInfoTable">事件信息表</param>
  public override void BindingEvent(DataTable eventInfoTable)
  {
      BindingEvent(this, eventInfoTable);
  }

  private void KzxLabel_Load(object sender, EventArgs e)
  {
      LayoutControl();
      //UpdateDelegate d = LayoutControl;
      //this.BeginInvoke(d);
  }

按鈕控件封裝

按鈕的封裝同上Label一樣，具體請移步《玩轉控件:擴展Dev中SimpleButton》.或者直接用Dev原生的SimpleButton亦可，此處不做過多廢話。只需在屬性配置區域的保存事件中，添加到流程圖展示區即可，配置區的按鈕保存代碼如下：

 BillInfo info = new BillInfo();
//info.sID = Edt_FrmBtn.EditValue.ToString();
info.sFrmName = Edt_FrmBtn.Text.ToString();
info.sFrmCaption = Edt_CaptionBtn.Text.Trim();
info.sMsgID = Edt_MsgBtn.Text.ToString().Trim();

if (bAddBtn)
{
    DevExpress.XtraEditors.SimpleButton sb = new DevExpress.XtraEditors.SimpleButton();
    sb.Left = int.Parse(Edt_LeftBtn.Text.Trim());
    sb.Top = int.Parse(Edt_TopBtn.Text.Trim());
    sb.Width = int.Parse(Edt_WidthBtn.Text.Trim());
    sb.Height = int.Parse(Edt_HightBtn.Text.Trim());
    sb.Name = Edt_FrmBtn.Text.Trim();
    sb.Text = Edt_CaptionBtn.Text.Trim();

    sb.Tag = info;

    sb.Image = picture1.Image;
    sb.ImageLocation = DevExpress.XtraEditors.ImageLocation.TopCenter;
    sb.Cursor = Cursors.Hand;
    sb.Visible = true;
    TabControl2.SelectedTabPage.Controls.Add(sb);

    sb.Click += onClick;
    MoveClass.BarcodeControl(sb);
    if (bFirstControl)
    {
        MoveClass.BarcodeCreate();
        bFirstControl = false;
    }
    this.TabControl2.Enabled = true;
    bAddBtn = false;

    this.kzxsBtnAddButton.Enabled = true;
    this.kzxsBtnAddLabel.Enabled = true;
    this.kzxsBtnAddLine.Enabled = true;
}
else if ((selectControl is DevExpress.XtraEditors.SimpleButton) && (DevExpress.XtraEditors.SimpleButton)selectControl != null)
{

}

以上便是"箭頭/直線","Label注釋","按鈕"等功能的准備工作，具體效果如圖：

再次強調，因時間和篇幅問題，作者沒有對代碼做嚴格的校驗，主要以實現功能為主。所以當您拿到源碼時需要根據實際情況自行完善，或者后續作者有時間也會繼續完善（工作996+的我太難了！）

各個模塊功能實現后，就是保存當前繪制的流程圖環節了，為了演示效果，作者沒有處理數據庫相關的工作，主要以DataTable來存儲相關繪制數據的。至於圖片，作者是用流的方式來存儲的，展示時解析即可。

#region 圖片處理
  /// <summary>
  /// 點擊上傳圖片
  /// </summary>
  /// <param name="sender"></param>
  /// <param name="e"></param>
  private void picture1_Click(object sender, EventArgs e)
  {
      if (this.openDialog1.ShowDialog() == DialogResult.OK)
      {
          picture1.Image = Image.FromFile(this.openDialog1.FileName);
      }
  }
  /// <summary>
  /// 用流的方式來存儲圖片
  /// </summary>
  /// <param name="img"></param>
  /// <returns></returns>
  private byte[] convertByte(Image img)
  {
      MemoryStream ms = new MemoryStream();
      img.Save(ms, img.RawFormat);
      byte[] bytes = ms.ToArray();
      ms.Close();
      return bytes;
  }
  private Image convertImg(byte[] datas)
  {
      MemoryStream ms = new MemoryStream(datas);
      Image img = Image.FromStream(ms, true);
      ms.Close();
      return img;
  }

  #endregion

DataTable數據存儲如下圖：

如上代碼TODO出需要根據自己實際完善，或者公眾號私信作者一起探討。

至此工作完成！一起來看看最終效果：

由於后續所有重寫/重繪控件都在同一個項目使用，而且Dev系統引用文件較多，壓縮后源碼文件仍然很大，如果有需要源碼的朋友，可以微信公眾號聯系博主，源碼可以免費贈予~！有疑問的也可以CALL我一起探討。

最后，感謝您的耐心陪伴！如果覺得本篇博文對您或者身邊朋友有幫助的，麻煩點個關注！贈人玫瑰，手留余香，您的支持就是我寫作最大的動力，感謝您的關注，期待和您一起探討！再會！（update:公眾號回復：Fucking ERP或者ERP 獲取源碼）
